Black Glass Nova is simply excellent!
I used to be a happy user of Tgx's original Black Glass - then Black Glass Nova was released and I haven't look backed since! The Nova version just adds a little something extra to the cool looking original, and I especially love the music screens, which I just find a little better compared to all other skins. With each release Tgx adds new cool details to the skin which currently pushes this skin a step closer to perfection. And most importantly... my girlfriend is able to navigate in Black Glass Nova which saves me from quite a bit frustration. A big recommendation to give Black Glass Nova a try!
